I have Dell Inspiron 3520 with 15.6' 780p screen (40-pin connector located on the left screen corner when looking from the back side)
I want to upgrade it to at least 1080p (I didn't find any 15.6 4k displays on ebay/amazon/newegg).
What is the best choice for in my case? The budget is 350$. I want it will be with 180 degree viewing angle
